  • 1H NMR spectra of 43 alleged psychedelic tryptamines (2-(1H-indol-3-yl)ethan-1-amines) and benzofuran analogues (2-(1-benzofuran-3-yl)ethan-1-amines) from grey-market internet vendors across North America and Europe were acquired and compared. Tryptamines having mono- or di- alkyl, cyclopropyl, or allyl amine substituents and/or substitution of the indole/benzofuran ring by acetyloxy, hydroxy, methoxy, or methyl groups were analysed. 1H NMR spectra for some of these compounds have not been previously reported to my knowledge. The spectrum of each analyte is consistent with the compound as labelled and sold. None of the analytes was found to be unequivocally misrepresented. This collection of experimentally uniform spectra may help forensic and harm-reduction organizations identify these compounds, some of which appear only sporadically. The complete spectra are provided as supplementary data.
